Battery Life Advisory
All modules in the MVI series use a rechargeable Lithium Vanadium Pentoxide battery to backup the 512K SRAM
memory, real-time clock, and CMOS. The battery should last for the life of the module.
The module must be powered for approximately twenty hours before it becomes fully charged. After it is fully charged,
the battery provides backup power for the CMOS setup and configuration data, the real-time clock, and the 512K
SRAM memory for approximately 21 days.
Before you remove a module from its power source, ensure that the battery within the module is fully charged. A fully
charged battery will hold the BIOS settings (after being removed from its power source) for a limited number of days.
When the battery is fully discharged, the module will revert to the default BIOS settings.
Note: The battery is not user replaceable.

In This Chapter
Installing and Configuring the Module ...................................................19
IP Address.............................................................................................22
Uploading and Downloading the Configuration File...............................23
In order for the MVI71-DNPSNET module to function, a minimum amount of
configuration data must be transferred to the module. A text file named
DNPSNET.CFG is shipped with the module. This file can serve as a starting
point to develop a user application. Edit the file to configure the module for the
application.
A terminal server program is used to upload and download the configuration file
to the module. An additional file, WATTCP.CFG, must be configured for the
specific network on which the module resides.
2.1 Installing and Configuring the Module
This chapter describes how to install and configure the module to work with your
application. The configuration process consists of the following steps.
1 Modify the module's configuration files to meet the needs of your application,
and copy the updated configuration to the module. Example configuration
files are provided on the CD-ROM. Refer to the Modifying the Example
Configuration File section, later in this chapter, for more information on the
configuration files.
2 Modify the example ladder logic to meet the needs of your application, and
copy the ladder logic to the processor. Example ladder logic files are provided
on the CD-ROM.
Note: If you are installing this module in an existing application, you can copy the necessary
elements from the example ladder logic into your application.
The rest of this chapter describes these steps in more detail.
Before installing and configuring the module, design the application. Determine
the number points for each data type. Review the Application Design section to
aid in application design.
It is now time to edit the DNPSNET.CFG file to set up the module for the specific
application. Refer to the Configuration File section of this document. Download
this configuration to the module along with the associated ladder logic.

The next step in installing and configuring the module is to define whether the
block transfer or side-connect interface will be utilized. If the block transfer
interface is to be used you should be ready to connect the module to the DNP
Ethernet network if the ladder logic is defined correctly. If the side-connect
interface is to be used, you must obtain the side-connect kit, which is sold
separately.
If the side-connect interface is utilized, make sure the file SC_DATA.TXT on the
Compact Flash Disk contains the correct first file number. You can run the
setdnpsc.exe program to set the file number to be used with your application.
Install the module in the rack and turn on the power. Connect the terminal server
to the module's debug/configuration port and exit the program by pressing the
Esc key followed by the 'X' key. This will cause the program to exit and remain at
the operating system prompt. Run the setdnpsc.exe program with a command
line argument of the file number to use for the first file. For example, to select
N10: as the first file, enter the following:
SETDNPSC 10
The program will build the SC_DATA.TXT on the Compact Flash Disk (C: drive in
the root directory).
Next, define the data files to be used with the application. If the block transfer
interface is used, define the data files to hold the user data (read and write data).
Enter the ladder logic to handle the blocks transferred between the module and
the PLC. Download the program to the PLC and test the program with the
module.
If the side-connect interface is used, no ladder logic is required for data transfer.
The user data files to interface with the module must reside in contiguous order
in the processor. The first file to be used by the interface is the status/control file.
This is file number set in the SC_DATA.TXT file using the SETDNPSC.EXE
program. The following table lists the files used by the side-connect interface:
File Number Example Size Description
Cfg File N10 100 Control/Status File
Cfg File+1 N11 to 1000 Data transferred from the module to the processor
Other files for read data
Cfg File+1+n N12 to 1000 Data transferred from the processor to the module
Cfg File+1+n+m Other files for write data
n is the number of read data files minus one. Each file contains up to 1000
words.
m is the number of write data files minus one. Each file contains up to 1000
words.
More than one read and/or write file may exist in an application. This is required
when more than 1000 words of data are required. Two examples are given for
the files used with different data set sizes:
